## How do you calculate power from torque?

- Torque (lb.in) = 63,025 x Power (HP) / Speed (RPM)
- Power (HP) = Torque (lb.in) x Speed (RPM) / 63,025.
- Torque (N.m) = 9.5488 x Power (kW) / Speed (RPM)
- Power (kW) = Torque (N.m) x Speed (RPM) / 9.5488.

**What is power associated with torque?**

(A) : Power associated with torque is product of torque and angular speed of the body about the axis of rotation. (R ) : Torque in rotational motion is analogue to force in translatory motion.

**Which of the following is the formula of power?**

P = E/t: This formula is also called the mechanical power equation. Here E stands for energy in joule and t stands for time in seconds. This formula states that the consumption of energy per unit of time is called power.

### What is the relation between torque and motor rated power?

Since the rated output power of a motor is a fixed value, speed and torque are inversely related. As output speed increases, the available output torque decreases proportionately. As the output torque increases, the output speed decreases proportionately.

**How do you find net torque from two forces?**

What is the Net Torque on an Object from Multiple Forces

- Torque: Torque is the rotational analog of force. It is a “twisting” force that causes an object to rotate.
- Sum of the Torques Equation: Στ=τ1+τ2+τ3+⋅⋅⋅+τn.
- Torque Equation: Torque is the cross product of the radius and the force. τ=r×F=rFsinθ τ = r × F = r F sin

**What is Net force formula?**

Net force is the sum of all forces acting on an object. The net force can be calculated using Newton’s second law, which states that F = ma, where: F is the net force. m is the mass of the object. a is acceleration.

## What does R mean in torque?

τ \tau τ is torque, F is applied force, r is the radius from the axis of rotation to the location where the force is exerted, and θ is the angle between F and r when these vectors are placed tail to tail.

**What is the formula for torque and HP?**

POWER = (TORQUE ÷ RADIUS) x (RPM x RADIUS x 2 x π) HP = TORQUE ÷ RADIUS x RPM x RADIUS x 2 x π ÷ 33,000 Note that at 5252 RPM, torque and HP are equal.

**What is the relationship between torque and power?**

TORQUE and RPM are the MEASURED quantities of engine output. POWER is CALCULATED from torque and RPM, by the following equation: (At the bottom of this page, the derivation of that equation is shown, for anyone interested.)

### How much torque is applied to the shaft of a shaft?

Because the shaft is fixed to the wall, the shaft does not turn, but there is a torque of 100 pounds-feet (100 pounds times 1 foot) applied to the shaft.

**What do the power lines mean on a torque curve?**

The solid lines show the power produced by the torque curves of the same color. Note that, with a torque peak of 587 lb-ft at 3000 RPM, the pink power line peaks at about 375 HP between 3500 and 3750 RPM.
